Aircraft shot blasting media glass microsphere AGB25 ABG30

AGB25 and ABG30 are high-strength solid glass microspheres specially engineered as professional shot blasting media for aerospace aircraft components. With uniform spherical shape and moderate hardness, they deliver controlled peening intensity to form stable compressive stress layers on alloy surfaces, enhancing fatigue resistance and corrosion protection for engine parts and airframe structures. These clean non-metallic microspheres leave no ferrous contamination, avoiding electrochemical risks on titanium alloys and high-temperature aviation materials. They feature excellent flowability for precise finishing on complex curved blades and precision parts, balancing surface smoothness and strengthening effect perfectly. AGB25 and ABG30 ensure consistent blasting performance, low residual magnetism and long service life, fully meeting strict aviation surface treatment standards.
